Archaic or rare: to appease, satisfy, or calm; to bring peace or quiet.
From Old French 'apaise,' from 'a-' + 'paiser' (to weigh, balance), related to 'peace,' suggesting the idea of balancing conflicts.
Medieval writers used 'apaise' where we'd now say 'appease,' but the shift in pronunciation and spelling gradually pushed this older form out of use.
